One nice thing about video poker is you can know the return of the machine even before you start playing.  On a typical video poker game, the casino's average profit on each play is about 3%.  That's called the house edge.  The return is the part that's returned to the player.  So if the casino gets 3% of all money bet, the players get back 97% of all money bet.  The return on a video poker machine is determined by the paytable.  Just compare the paytable to the list at Wizard of Odds and you'll see that, for example, the Jacks or Better paytable above means that the return on that machine is 99.54%.  If the paytable showed only 8 coins for the full house and only 5 for the flush, it would be a 97.3% machine.
JOKER POKER – Also know as ‘Joker’s Wild’, is played with a deck containing 53 cards in which one of them is a joker and can be used as any card when drawn. The lowest possible winning hand is a pair of kings, and Five of a Kind and a Wild Royal Flush are added to the the mix just as with Deuces Wild. Again, if the pay table is set correctly, the player actually has a 0.64 percent edge over the house with perfect strategy. There are also self-explanatory sub-variations of Joker Poker known as Kings or Better, or Two Pairs or Better.
This guide will only cover one version of Double Double Jackpot Poker. Double Double Jackpot Poker bumps the higher pays by doubling the Double Jackpot Poker pays for all four of a kind hands except 2’s through 10’s which are two and a half times the Double Jackpot Version. The pays for a full house, a flush and a straight all have the pays increased by one. The pay for two pairs is reduced to even money to make up for the other increases. The return for this game is 100.35 percent but the variance increases dramatically to 38.2 from 22.4
The strategy charts for all non-wild card games are organized the same way. The hand with the highest average return goes at the top of the strategy chart. For most video poker pay tables that hand is the royal flush. It is followed by lower paying hands and partial hands in order of decreasing return. Keep in mind that partial hands that are not winners themselves will at times be included above hands that are winners because they have an average return (for all possible outcomes) that is higher than a dealt winning hand. For example, in most games four cards of a royal flush is listed above a full house because of the possibility of that hand turning into a royal flush. However, that is not the only hand that can be made from a hand with four cards of a royal flush. There is also the possibility that the hand could become a straight flush, a flush, or a straight with the proper cards being drawn. See the examples below.
Understand your average loss. As well as understanding possibilities in a game of poker, it's good to keep in mind what your average loss during a session of video poker will be, so you go in with realistic expectations. To determine your average loss multiply the house end(the return the casino makes) by the bet size by the number of rounds per hour.[6]
Holding cards based on what you feel is correct or holding based on the flow of the cards are both technically strategies. But the video poker game manufacturers set up pay tables based on the math of the game so the casinos will be sure to make a profit from them. Therefore in order for you to make the most of your video poker playing experience, you need to use a strategy that is based on the same math.
If you visit the Wizard of Odds site, you can find a free video poker game available in your browser window that includes auto-hold features and warnings when you’re about to make a mistake. This is a free Jacks or Better 9/6 game: http://wizardofodds.com/play/video-poker/. You can even update the pay tables for this game to something other than 9/6 Jacks or Better. For the price, this training program is hard to beat. The game also features a “more games” button which opens up a screen where you can choose from three dozen different games, including the following:
A straight is a hand with consecutive ranks, like 9? 7? 10? 8? 6?.  Notice again that the cards don't have to appear in order.  The order of face cards, from lowest to highest, is Jack, Queen, King, Ace, which we abbreviate J, Q, K, A.  An ace can also count as 1, to complete a straight where the other cards are 2, 3, 4, and 5.  But it can't count as both a low and a high card, e.g., Q K A 2 3.
Since video poker is a game of strategy, it definitely pays to get some practice in before you start playing for real by trying free online video poker. This isn’t possible in a brick-and-mortar casino, but online casinos give you the chance to play for free for as long as you want. This lets learn how to play video poker without putting any of your money at risk.

Practicing video poker strategy by using a computer program or smartphone / tablet app is far more effective than practicing manually as described in section 7.2. The only real problems that might get in the way of you doing so are that you need a computer or smartphone / tablet and you need the program or application. As mentioned previously, there are several good video poker programs and applications available. They are also quite reasonably priced. If you do not have a video poker application, I strongly suggest you purchase one as soon as you can. You can practice manually for a while until you receive it, so you will not be just sitting around and doing nothing while you wait.
All possible resulting hands and pays for a hold of just the ace of hearts must be calculated. The same must then be done for a save of just the 3 of spades, the 4 of hearts, the 5 of clubs, and the king of diamonds. Then the same must be done for each possible hold of two cards. Then the same is done for holds of three cards. The same is done for holds of four cards. Finally the return for a hold of all five cards is calculated. The returns are then compared in order to select the best possible hold (in terms of money returned). The results for each of the over two and a half million possible hands are summarized in order to develop the strategy.
You learned in chapter 3.4 that the variance of a multiple play game increases as the number of lines played increases. The variance of a single play game is lower than the variance of a three play game. The variance of a five play game is higher than the variance of a three play game, and so on. In this section you will find out specific bankroll sizes for a couple of games at a different number plays for each game.
Playing hunches or streaks may work for a hand or two (or possibly even a session or two), but far more often these tactics will not work. In fact, by employing these types of playing strategies, you will end up giving the casino even more of your hard earned money than you need to. Only by using mathematically derived video poker playing strategies will you get every cent you can from your video poker play over the long run.
In this chapter you learned how video poker strategy charts are created. The process is very computationally intense. By using the math of video poker to create a strategy that maximizes the return of every hand, the resultant strategy will have the highest return possible. You also learned that while there may be scores of lines in a strategy chart, the charts are straightforward to use. In order to properly use a strategy chart the video poker player must know the relative amount paid for each different hand. They must also know how to determine whether a straight or straight flush is a fully open or an inside hand. Having learned how to use a video poker strategy chart, you are ready to learn how to practice playing video poker in order to learn how to play without having to check a strategy chart for each hand. You will learn how to do this in chapter 7.
Pick a game. There are dozens of different video-poker games in casinos. Different games will have different rate of returns, meaning some games, if you win, will give you a higher percentage of your money back and others will give you a lower percentage. A "9/6 Jacks or Better" paytable is the best because the rate of return is 99.54%, meaning the casino only keeps .46% of your money.[1]
Stick to the proper way of how to play video poker as well as video poker strategy and you won't necessarily be able to become a professional video poker player, but if you're looking for the one casino game besides traditional poker where you can get positive expected value, or at least a very low house advantage giving you hours of play for a very small investment, video poker may be your game. 
Less interesting and less impressive was the page about “Video Poker’s Greatest Hits”. (http://www.videopoker.com/greatest_hits/) One of the aspects I found disappointing about this sales page was the lack of a price listing. There’s a button for a free trial, and another “buy now” button, but I don’t think I should have to click “buy now” to get a price. I did click through, and the price is only $19.95, but the software is limited to 8 video poker games.
